When it appears that you have killed the monster, NEVER check to see if it's really dead. It isn't.

Never read a book of demon summoning aloud, even as a joke.

Do not search the basement, especially if the power has just gone out.

If your children speak to you in Latin or any other language which they should not know 'RUN!!....RUN!!.

As a general rule, don't solve puzzles that open portals to Hell.

If you're searching for something that caused a noise and find out that it's just the cat, leave the room immediately if you value your life.

If you find a town that looks deserted, it's probably for a reason. Take the hint and leave NOW!!

Don't fool with recombinant DNA technology unless you're sure you know what you are doing. Even then, don't do it.

If you're running from the monster, expect to trip or fall down at least twice, more if you are of a female. Even though you may be faster than the monster, you can be sure that it WILL catch you.

If your friends suddenly begin to exhibit uncharacteristic behavior such as hissing, fascination for blood, glowing eyes, increasing hairiness, and so on, get away from them as fast as possible.

Stay away from certain geographical locations, some of which are listed here: Amityville, Elm Street, Transylvania, Meskatonic University, Camp Crystal Lake, Haddonfield, Illinois, one gas station desert towns or any small town in Maine.

If your car runs out of gas at night, do not go to the nearby deserted-looking house to phone for help.

Beware of strangers bearing tools such as chainsaws, staple guns, hedge trimmers, electric carving knives, combines, lawnmowers, butane torches, soldering irons, or band saws. This is especially true if they are wearing a hockey mask or one made of human skin.
